Safran is using its Paris display to highlight several new technologies.

Leap

Making its world air show debut - in full-size mock-up - will be the CFM International Leap turbofan that CFM partners Safran and General Electric are developing to replace their venerable CFM56 powerplant as used on Airbus A320s and Boeing 737s. Visitors will get a good look at two of Safran's key contributions to the project, the 3D woven composite fan blades, featuring Safran's resin transfer moulding process, which promises composite parts that are both light and robust, using a process that is easy to apply on an industrial scale.

Also on show, from Safran's Aircelle division, is the Leap integrated nacelle and thrust reverser, which also features 3D woven composites with advanced anti-icing and acoustic design. "The nacelle is a component that is as difficult [to engineer] as the engine," says Leclère.

Arriel 2

Also in mock-up will be the new Turbomeca Arriel 2D rotorcraft engine, recently certificated by the European Aviation Safety Agency. The engine promises to reduce maintenance costs and fuel consumption compared with the existing version through innovations including a new design for the axial compressor, new monocrystal material for the high-pressure turbine blades. At service entry in the second half of 2011, on the Eurocopter AS350 B3e, time between overhauls will be 4,000h, rising to 6,000h at maturity.

Green taxiing

Safran has developed a concept dubbed "green taxiing" that allows an aircraft to taxi without having to use its jet engines. Electric motors located in the wheels on the main landing gear allow an aircraft to advance, or even reverse. This new technology will cut gate-to-gate fuel consumption and emissions on an average single-aisle jet on trips of up to 925km (500nm) by up to 5% and, says Leclère, will benefit operators by offering push-back on demand - without being reliant on a tractor. A demonstrator should be ready in 2012, with the system entering service in mid-2016.

Morpho Way

From Safran's Morpho division, an automated and semi-automated systems to read biometric data on passports and travel documents promises improved security and faster airport check-in.

CTX 5800 X-ray detection

With Safran's X-ray detection system making its air show debut at Paris, passengers will be able to carry liquids and gels through airport security; the system also promises to speed inspection, improving the detection rate and reducing the number of false positives.
